Updating aliases does not re-create container or update auto-discovery

[jeanpralo]

Hi there,

Considering two docker-compose files:

/tmp/dc1/docker-compose.yml:

version: "2"

services:
  foo:
    image: busybox
    command: sleep 600
    networks:
      default:
        aliases:
          - foo1

and /tmp/dc2/docker-compose.yml:

version: '2'

services:
  bar:
    image: busybox
    command: sleep 600

networks:
  default:
   external:
     name: dc1_default

So my app dc2 wants to use the default network of my app dc1, if i try to resolve foo and foo1 from bar I have no problem.

Now I want to add an alias foo2 to foo, so I update my dc1 docker-compose.yml file which looks like that:

version: "2"

services:
  foo:
    image: busybox
    command: sleep 600
    networks:
      default:
        aliases:
          - foo1
          - foo2

And I run a docker-compose up -d in the directory:

docker-compose up -d
dc1_foo_1 is up-to-date

If I try to resolve foo2 from dc2_bar_1 it does not work, I need to delete dc1_foo_1 and re-create it.

Thanks for the bug report. You're correct that nothing under networks is being considered in the config hash. Should be an easy fix for the next release.
